Features of RHEV
With RHEV, you can virtualize even the most demanding application workloads with fea-
tures including the following:
• Host scalability : This supports a limit of up to 160 logical CPUs and 2 TB per
host (platform capable of up to 4,096 logical CPUs / 64 TB per host)
• Guest scalability : This supports up to 160 vCPU and 2 TB VRAM per guest
• KSM memory over commitment : This allows administrators to define more
RAM in their VMs than what is present in a physical host
• Security : This supports SELinux and new sVirt capabilities, including Mandatory
Access Control ( MAC ) for enhanced virtual machine and hypervisor security
• Management : This provides centralized enterprise-grade virtualization manage-
ment engines with a graphical administration console and programming interfaces
• Live migration : This allows running virtual machines to be moved seamlessly
from one host to another
• High availability : This allows critical VMs to be restarted on another host in the
event of hardware failure with three levels of priority
• System scheduler : This provides system scheduler policies for load balancing to
automatically balance the VM load among hosts in a cluster
• Power saver : The power saver mode is used to consolidate VM loads onto fewer
hosts during nonpeak hours
• Maintenance manager : This allows you to move the hypervisor into the mainten-
ance mode for any software or hardware updates of the hypervisor
• Image management : This supports template-based provisioning, live virtual ma-
chine snapshots, and cloning new virtual machines from snapshots
• Monitoring and reporting : This provides a suite of preconfigured reports and
dashboards and creates your own ad hoc reports that enable you to monitor the sys-
tem
• OVF import/export : This allows you to import and export Open Virtualization
Format ( OVF ) virtual machines into RHEV
• V2V : This automates the conversion of the VMware or Xen virtual machine im-
ages into an OVF file for use within RHEV
